T-SQL, or Transact-SQL, was made by Microsoft as an extension of SQL (Structured Query Language). It is used to search for, add, update, and change information on Microsoft SQL Server and Azure SQL Database. T-SQL has extra features like procedural programming, local variables, and different methods that make it faster and more flexible.
Database managers, data analysts, data engineers, SQL developers, business analysts, and anyone else who wants to work with Microsoft SQL Server or Azure SQL Database can learn from a T-SQL course.
Even though there are no hard requirements to take a T-SQL course, you should have a basic knowledge of databases and be familiar with SQL.
A T-SQL course typically covers the following topics:
- Introduction to T-SQL and its differences from standard SQL
- Data definition and manipulation using T-SQL (e.g., SELECT, INSERT, UPDATE, DELETE)
- Using JOINs, subqueries, and CTEs (Common Table Expressions) for complex queries
- T-SQL functions, such as aggregate functions, window functions, and system functions
- Procedural programming concepts, including variables, control structures, and error handling
- Creating and using stored procedures, triggers, and user-defined functions
- Transaction management and concurrency control
- Performance optimization techniques and best practices
The length of a T-SQL study depends on the course provider, the way the course is set up, and the speed at which the student learns. T-SQL classes usually last anywhere from a few days to a few weeks.
Yes, there are certifications offered that include T-SQL as a focus. Microsoft offers the Microsoft Certified: Azure Database Administrator Associate certification and the Microsoft Certified: Azure Data Engineer Associate certification. Both of these certifications require that you know T-SQL.
The price of a T-SQL course can vary a lot based on who is teaching it, what it covers, and how it is taught (in person or online). Some online tools are free, while comprehensive in-person training programs can cost hundreds or even thousands of dollars.
After taking a T-SQL training, people can look for jobs as SQL developers, database administrators, data analysts, data engineers, or business analysts who specialize in Microsoft SQL Server or Azure SQL Database. T-SQL knowledge is a useful skill in the job market for many industries that use Microsoft's database technologies.
